Some of the Varied Applications of Zein


Encapsulation – a ZEIN coating will provide a very functional protective surface against moisture and edible fats escaping from within.  Conversely it will protect from external moisture and fats protecting from oxidation and rancidity.  Can encapsulate anything that can be reduced to a granule in food or pharmaceuticals, including nut meat, flavors, colors, sweeteners


Enteric Coating – ZEIN use can duplicate all functions of Alcohol Soluble SHELLAC.  It is a natural alternative to chemical coatings to mask the taste of pharmaceuticals. Additionally, it can be used for time release preparations.


Adhesive - When ZEIN is first sprayed and before it dries, there is a tackiness to the freshly applied film. Many additives can be sprayed onto this tacky surface. When dried, the added particles are securely adhering to the treated surface.  Many such uses allow for markedly lower quantities of these additives.


Increases Shelf Life - ZEIN can be used as a moisture barrier and protective microbial resistant barrier for food, pharmaceuticals and nutraceuticals.  Delays rancidity and increases shelf life for fresh fruits and vegetables, as well as baked goods.


Electrophoresis Integrity – used in the chrome plating repair process for the aeronautic industry.
